For some days I m getting warning saying USB device not recognized. It says one of the USB has malfunctioned.

I have two USB port and both of them is used (one for mouse and one for cable).
And when I click on the mesaage it says "unkown device", which i even deleted from the device manager and still shows up.
This has slowed down the performance.
Any idea to solve?
Thanks

Hi, Remove USB devices from the USB connectors one at the time until the warning goes away. If no help then disable the UNKNOWN device in System Manager util you can locate the problem. When you remove a device from Sys Manager and reboot the drvice is reinstalled from Plug and Prays driver folder. All devices are unknow to PLUG AND PRAY util the device in question answers the system call and identifies itself. No answer = permanent UNKNOWN DEVICE.
Good Luck, Jim

Do you have a fingerprint reader or cam built into your laptop? What about a memory card reader?
